Joanna Jedrzejczyk poured on the pressure in the championship rounds to claim a thrilling win

A dominant third round followed for the champion, as Jedrzejczyk came storming back into the fight using her blistering hand speed and thumping front kicks, before repeating the feat on an increasingly exhausted Gadelha in the fourth.

And while Gadelha rallied and made the final frame far more competitive than the previous two, it was Jedrzejczyk who outstruck the challenger down the stretch to score a memorable win in one of the best women's fights ever witnessed in the UFC Octagon.

But when Choi managed to wriggle back to his feet the fight turned spectacularly in his favour.

After throwing out a couple of range-finders, Choi threw a beautiful one-two combo that sent the Brazilian crashing to the mat. Another big shot to the grounded Tavares was more than enough for referee Herb Dean, who dived in to call a stop to the fight as the Las Vegas crowd roared its approval.

Matthews was the betting favourite going into the bout, but Lee utilised his wrestling pedigree to take the Australian prospect to the mat before flattening him out and finishing him with ground strikes.

After the bout, Lee called on the UFC to make a match between him and New Yorker 'Raging' Al Iaquinta at the UFC's upcoming UFC 205 event at Madison Square Garden.
